TECHNICAL FIELD

The present invention relates to tinctures for infusion into food, beverage, cosmetic or drug products and more specifically to a new and useful tincture for infusion containing homeopathic and anti-oxidative agents. The present invention further relates to methods for adding sufficient amount of tincture to provide sufficient and bioavailable amounts of homeopathic and anti-oxidative agents to a food, beverage, cosmetic or drug product, with minimal effect on the food, beverage, cosmetic or drug product's alcohol by volume (ABV).

BACKGROUND

Wine has played a positive role in maintaining human health by providing a sanitary source of water, through its psychoactive effects on the state of one's mind and by providing a reliable source of calories. In the early 1970's, the scientific and medical communities began taking an interest in the human health benefits of antioxidants including polyphenols. In 2003, trans-resveratrol was brought to the public's attention once it was reported that trans-resveratrol had life-extending properties. Concurrently it was advertised that trans-resveratrol is abundantly available in red wines as a result of the anti-oxidant being present in the skins of red grapes.

With the intense interest in the health benefits of resveratrol by the scientific and medical communities has come a concurrent interest in the free market promotion of these proposed benefits. A 2008 study of the red wine market in Spain demonstrated that consumers were willing to pay a higher price for a resveratrol enhanced red wine than for its non-enhanced counterpart. Since then, many attempts have been made to enhance or add resveratrol to food and beverages to provide its health benefits.

There have been many forms of resveratrol enhanced products introduced to the market, but none provide for the resveratrol to be bioavailable for appropriate absorption by the human body, thus the “enhanced” qualities of the food or beverage becomes digested without being absorbed by the human body. Instead of being absorbed, the resveratrol additive is digested and eventually expelled from the body without significant absorption, thus making the enhancement of the food or beverage non-effective. Typically, resveratrol enhanced products simply include an amount of resveratrol powder being added to the normal ingredients of the food or beverage since the resveratrol powder adds very little to no flavor.

Currently, the common form of bioavailable resveratrol available to the consumer is provided from drinking red wine. It should be appreciated that merely ingesting an amount of resveratrol, whether in raw powder form, pill form, or as a suspended solid immixed within a liquid provides no known bioavailability, thus the ingested resveratrol is digested and excreted without being available to the cells of the body. In fact, recent studies (Walle et al, Drug Metabolism and Disposition Vol 32, No. 12, pgs. 1377-1382 Jun. 7, 2004) have provided that “[a]ll attempts to find measurable levels of Resveratrol in plasma after the oral dose at any time point in [patients] failed.” In oral dose scenarios, the free resveratrol essentially never makes it into the bloodstream.

A number of attempts have been made to provide for resveratrol-enhanced beverages, however, many teach simply adding an amount of resveratrol powder to a beverage. These attempts fail to provide a resveratrol enhanced beverage because the resveratrol added is not bioavailable, rather it only becomes a suspended solid forming an aqueous solution, and becomes digested and excreted from the body without being absorbed by the body.

Thus, there remains an unmet need at providing a resveratrol enhanced food, beverage, cosmetic or drug product that provides for a bioavailable amount of resveratrol to provide the homeopathic and anti-oxidative benefits of resveratrol. There further remains an unmet need at providing an effective resveratrol enhanced food, beverage, cosmetic or drug product that provides a bioavailable amount of resveratrol while maintaining the alcohol by volume (ABV) of the enhanced food, beverage, cosmetic or drug product below any regulatory standards for required reporting.

SUMMARY OF INVENTION

A tincture of trans-resveratrol in a food grade or pharmaceutical grade ethanol base is provided. The ethanol and resveratrol tincture is added to any beverage for infusing a bioavailable dose of resveratrol to the beverage. A method of making a tincture of resveratrol and a solvent containing ethanol is also provided that includes mixing an amount of resveratrol with an amount of the solvent containing ethanol to form a mixture, agitating the resveratrol and solvent mixture dissolving the resveratrol into solution. The tincture is used to infuse a bioavailable dose of resveratrol into a food, beverage, cosmetic or drug product.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following detailed description is merely exemplary in nature and is in no way intended to limit the scope of the invention, its application, or uses, which may vary. The invention is described with relation to the non-limiting definitions and terminology included herein. These definitions and terminology are not designed to function as a limitation on the scope or practice of the invention, but are presented for illustrative and descriptive purposes only.

Various terms used throughout the specification and claims are defined as set forth below as it may be helpful to an understanding of the invention.

As used herein “mixture” shall mean a physical combination of two or more substances on which the identities are retained and are mixed but are not combined chemically.

As used herein, “food” or “beverage” may alternatively be a food, beverage, cosmetic or drug product.

As used herein, “ethanol” shall mean pure ethanol or a solvent containing a majority by weight of ethanol.

As used herein “tincture” shall mean an alcohol concentrate along with other materials that is used as an additive for a food or beverage.

As used herein “non-alcoholic beverage” shall mean a beverage having an alcoholic content by volume between 0.0% alcohol by volume (ABV) and 2.8% ABV. In some embodiments of the present invention, a “non-alcoholic beverage” is between 0.0% and 0.5% ABV.

As used herein “alcoholic beverage” shall mean any beverage with ABV content greater than that amount which is considered to be a non-alcoholic beverage.

As used herein “resveratrol” shall mean trans-resveratrol, cis-resveratrol, or dihydro-resveratrol. Trans-resveratrol having the structure provided in formula (I):

As used herein “bioavailable” shall mean the amount of a particular dose of a drug product that is available within the blood stream for absorption or metabolization. In terms of resveratrol, bioavailable shall mean free trans-resveratrol and/or its conjugate forms or derivatives thereof available in a mixture or tincture.

The present invention provides a tincture which includes resveratrol and ethanol to be infused with a food or beverage. It should be appreciated that by creating a resveratrol/ethanol solution that a bioavailable dose of resveratrol may be delivered to a subject orally. Without intending to be bound to a particular theory, it is believed that resveratrol becomes hydrogen bonded upon making a solution with ethanol in the present invention, the hydrogen bonded resveratrol can be added to any food or beverage and provide similar bioavailability as the tincture itself. It is further believed that the hydrogen bonded resveratrol is easier metabolized by the body, thus causing the resveratrol to be absorbed into the bloodstream and increasing its bioavailability. In at least one embodiment a tincture is made of a solution of resveratrol and a solvent containing an amount of ethanol where the tincture is a homogeneous (single-phase) solution with the resveratrol solute hydrogen bonded to the solvent ethanol.

Several methods for making a tincture to provide a bioavailable amount of resveratrol are provided herein. A tincture of resveratrol and ethanol is formed by mixing an amount of resveratrol with an amount of ethanol to form a mixture and agitating the resveratrol and ethanol mixture dissolving the resveratrol into solution. In at least one embodiment of the present invention, the ethanol is of food grade or pharmacy grade ethanol. In at least one embodiment of the present invention, the ethanol added to the tincture should be between 5% and 100% ethanol. In at least one embodiment of the present invention, the ethanol is at least 160 proof. In at least one embodiment of the present invention, the ethanol is 200 proof.

It is to be understood that in instances where a range of values are provided that the range is intended to encompass not only the end point values of the range but also intermediate values of the range as explicitly being included within the range and varying by the last significant figure of the range. By way of example, a recited range of from 1 to 4 is intended to include 1-2, 1-3, 2-4, 3-4, and 1-4.

It should be appreciated that while one may ingest an undiluted bioavailable tincture of resveratrol and ethanol directly, that such a high level of alcohol delivered directly to the body may have harmful effects which counteract the benefits from delivering bioavailable resveratrol. It is understood in the art that pure alcohol involves benzene azeotrope and is generally not for consumption. In at least one embodiment of the present invention, the tincture may be added to a food or beverage. In at least one embodiment of the present invention, the tincture is added after all processing, distilling or heating has been performed on a food or beverage. In at least one embodiment of the present invention, the tincture is added to a food or beverage at the point of service of the food or beverage.

In some embodiments of the present invention, the tincture may be diluted with water. For example a resveratrol concentration in a solvent of: a) 100% ethanol may be between 0 and 42 grams per liter of ethanol; b) 90% ethanol and 10% water may be between 0 and 32 grams per liter of ethanol; c) 80% ethanol and 20% water may be between 0 and 22 grams per liter of ethanol; d) 70% ethanol and 30% water is between 0 and 13 grams per liter of ethanol; e) 60% ethanol and 40% water is between 0 and 6.5 grams per liter of ethanol; 50% ethanol and 50% water is between 0 and 2.5 grams per liter of ethanol; f) 40% ethanol and 60% water is between 0 and 800 milligrams per liter of ethanol; g) 30% ethanol and 70% water is between 0 and 250 milligrams per liter of ethanol; h) 20% ethanol and 80% water is between 0 and 70 milligrams per liter of ethanol; i) 10% ethanol and 90% water is between 0 and 35 milligrams per liter of ethanol; and j) 5% ethanol and 95% water is between 0 and 18 milligrams per liter of ethanol.

Other additives may be introduced to the tincture to provide flavoring or other health benefits. In at least one embodiment of the present invention, the tincture may include one or more additional additives. In at least one embodiment of the present invention, additional additives may be water, spices, vitamins and minerals, color additives, flavor additives, or combinations thereof. In at least one embodiment spices may include pumpkin spice, cinnamon, sugar, sage, vanilla bean extract, or combinations thereof. In at least one embodiment, vitamins and minerals may include Thiamine hydrochloride, riboflavin (Vitamin B2), niacin, niacin amide, folate or folic acid, beta carotene, potassium iodide, iron or ferrous sulfate, alpha tocopherols, ascorbic acid, Vitamin D, amino acids (L-tryptophan, L-lysine, L-leucine, L-methionine), or combinations thereof. In at least one embodiment, color additives may include Orange B, Citrus Red No. 2, annatto extract, beta-carotene, grape skin extract, cochineal extract or carmine, paprika oleoresin, caramel color, fruit and vegetable juices or saffron. In at least one embodiment, flavor additives may be vinegar, citric acid, tartaric acid, malic acid, fumaric acid, lactic acid, high fructose corn syrup, hydrolyzed proteins, artificial sweeteners, or food extracts.

In some embodiments of the present invention the amount of resveratrol delivered in a tincture is to be of sufficient doses that are known to provide the health benefits associated with resveratrol. In at least one embodiment, the resveratrol concentration is between 0.001 and 42 grams per liter of ethanol. In at least one embodiment of the present invention, the resveratrol concentration is between 1 and 18 milligrams per liter of ethanol. In at least one embodiment of the present invention, 1 to 100 milliliters of a 0.001 to 42 gram resveratrol per liter of ethanol tincture is added to a 12 ounce beverage. In at least one embodiment 1 to 10 milliliters of the resveratrol tincture is added to a 12 ounce beverage. Not being bound to any particular theory, a 25 mg dose of bioavailable trans-resveratrol is equivalent to 10-25 servings of red wine, understanding that red wines have variable amounts of bioavailable trans-resveratrol. Example 9, for instance, the red wine used for testing bioavailable trans-resveratrol was below the detection limits of the measuring device, while adding the inventive tincture provided 450 times more bioavailable resveratrol than what appeared in the red wine without the tincture.

It should be appreciated that by adding an amount of tincture to a food or beverage may affect the alcohol content for which a food or beverage has been approved, or is desired. Thus, the present invention provides for a method of infusing a tincture of ethanol and resveratrol in a food or beverage, with minimal effect on the alcohol content of the food or beverage. In at least one embodiment of the present invention, a tincture of ethanol and resveratrol is prepared and added to a beverage, and allowed sufficient time for the tincture to infuse with the beverage. In at least one embodiment of the present invention, the amount of tincture added to the beverage changes the amount of alcohol by volume (ABV) of the beverage between 0.01% and 1.0%. In at least one embodiment of the present invention, the amount of tincture changes the ABV of the beverage between 0.02% and 0.5%.

In certain embodiments of the present invention, the beverage is a non-alcoholic beverage. In at least one embodiment of the present invention, an amount of 10 milligram per liter tincture is added to a 12 ounce non-alcoholic beverage thus providing a bioavailable amount of resveratrol while minimally changing the alcohol by volume of the non-alcoholic beverage from 0.0% to 0.02%. In at least one embodiment of the present invention, a 0.1 milliliter dose of tincture is added to a 12 ounce non-alcoholic beverage thus providing a bioavailable amount of resveratrol while minimally changing the alcohol by volume of the non-alcoholic beverage from 0.0% to 0.02%. In at least one embodiment of the present invention, an amount of 100 milligram per liter tincture is added to a 12 ounce non-alcoholic beverage thus providing a bioavailable amount of resveratrol while minimally changing the alcohol by volume of the non-alcoholic beverage from 0.0% to 0.2%. In at least one embodiment of the present invention, a 1 milliliter dose of tincture is added to a 12 ounce non-alcoholic beverage thus providing a bioavailable amount of resveratrol while minimally changing the alcohol by volume of the non-alcoholic beverage from 0.0% to 0.2%.

In other embodiments of the present invention, the beverage is an alcoholic beverage. In at least one embodiment an amount of a 10 milligram per liter tincture is added to a 12 ounce alcoholic beverage thus providing a bioavailable amount of resveratrol while minimally changing the alcohol by volume of the alcoholic beverage from 5.0% to 5.02%. In at least one embodiment a 0 1 milliliter dose of tincture is added to a 12 ounce alcoholic beverage thus providing a bioavailable amount of resveratrol while minimally changing the alcohol by volume of the alcoholic beverage from 5.0% to 5.02%. In at least one embodiment an amount of a 100 milligram per liter tincture is added to a 12 ounce alcoholic beverage thus providing a bioavailable amount of resveratrol while minimally changing the alcohol by volume of the alcoholic beverage from 5.0% to 5.2%. In at least one embodiment a 1 0 milliliter dose of tincture is added to a 12 ounce alcoholic beverage thus providing a bioavailable amount of resveratrol while minimally changing the alcohol by volume of the alcoholic beverage from 5.0% to 5.2%.

In at least one embodiment, the tincture for a beverage infusion with 42 grams of resveratrol and a solvent containing 0% water and 100% (200 proof) ethanol with a saturation of 42 g/L. In at least one embodiment a solution containing 42 grams of resveratrol in liter of solvent containing 100% (200 proof) ethanol is passable through a 10 micron filter. In at least one embodiment the amount of bioavailable resveratrol present in a beverage containing the resveratrol tincture is 25 milligrams. In at least one embodiment 0.6 milliliters of tincture is added to a 355 milliliter (12 ounce) beverage to deliver a resveratrol dose of 25 milligrams. In at least one embodiment, the tincture for a food infusion is a solvent of 70% water and 30% ethanol, yielding 250 mg of resveratrol per liter of tincture.

EXAMPLES

It is to be understood that while the invention has been described in conjunction with the detailed description thereof, the foregoing description is intended to illustrate and not limit the scope of the invention, which is defined by the scope of the appended claims. Other aspects, advantages, and modifications are within the scope of the following claims.

Example 1

A tincture of resveratrol and ethanol is made by immixing resveratrol and ethanol to provide 100 milligrams of resveratrol per liter of ethanol. A beer containing 5.0% ABV is poured into a glass. A direct measure of 0.1 mL dose of tincture is added to the 12 ounce beer. The added tincture raises the ABV of the beer to 5.02% while providing a bioavailable dose of resveratrol.

Example 2

Example 1 is repeated, but instead using a high-end mega-dose of 1.0 mL of tincture raising the ABV of the beer with tincture to 5.2%.

Example 3

A tincture of resveratrol and ethanol is made by immixing resveratrol and ethanol to provide 100 milligrams of resveratrol per liter of ethanol. A 12 ounce glass of water is poured and a syringe is used to measure a 0.1 mL dose of tincture and is added to the 12 ounces of water. The addition of the tincture raises the ABV of the water is raised to 0.02% while providing a bioavailable dose of resveratrol.

Example 4

Example 3 is repeated, but instead using a high-end mega-dose of 1.0 mL of tincture raising the ABV of the water with tincture to 0.2%.

Example 5

FIG. 2 provides a method for making a tincture. First 201 approximately 420 milligrams of trans-resveratrol powder is weighed. Next 202 an amount of solvent containing 10 milliliters of pharmacy grade ethanol is measured, immixed and agitated with the 201 approximately 420 milligrams of trans-resveratrol powder. The solution is agitated causing an amount of 203 the trans-resveratrol powder to dissolve in the solvent. The mixed solution appears 205 golden yellow in color that contains 42 milligrams trans-resveratrol per milliliter of ethanol contained in the solvent.

Example 6

Example 5 is repeated, but includes the additional step 204 of passing the solution through a 10 micron filter to remove any undissolved resveratrol and any other impurities contained in the resveratrol powder.

Example 7

A tincture is made containing concentrated (near-saturated at 25° C.) resveratrol and ethanol tinctures of 420 mg/10 mL (42.0 mg/mL). To deliver a 25 mg dose, 0.60 mL of tincture is required regardless of volume of beverage.

Example 8

A tincture of trans-resveratrol with ethanol is prepared with food grade or pharmaceutical grade 180 to 200 proof ethanol. Observations under multiple environmental settings confirmed the stability of the tincture created. Using medical grade measuring devices, the tincture was added to various beverages in volumes necessary to replicate and exceed the amount of trans-resveratrol in a typical serving of red wine from the Mediterranean stock. Observations demonstrated that there was no precipitation, no change in color, no change in taste and calculations confirmed that the amount of increase in alcohol by volume was maintained below any regulatory standards for required reporting.

Example 9

A tincture of trans-resveratrol with ethanol is prepared with food grade 200 proof ethanol. The trans-resveratrol tincture is was prepared by adding 421.5 mg trans-resveratrol to 10 mL of 200 proof (100%) food grade ethanol. This resulted in a clear, golden-colored solution with concentration of 42.15 mg/mL.

A dose of 25 mg of trans-resveratrol is delivered to a serving volume of various drinks including red wine, white wine, beer (Yuengling), spirits such as vodka and bourbon (Jim Beam), energy drinks (5 Hour Energy), sodas (diet Coke, Coke, Sprite) and orange juice (Tropicana). To deliver 25 mg of trans-resveratrol, 0.60 milliliters of trans-resveratrol tincture is required (42.15 mg/mL×0.60 mL=25.29 mg). An amount of the trans-resveratrol tincture is added to each beverage and is calculated based on the volume of the serving. The serving volume for a glass of wine is 187 mL. The serving volume for a glass of wine plus the 0.60 mL of trans-resveratrol tincture was divided by the dose of trans resveratrol 25.29 mg/187.6 mL=0.1348 mg/mL. 0.1348 mg/mL was then multiplied by 1000 ug/mg to get the amount in ug/mL, 0.1348 mg/mL×1000 ug/mg=134.8 ug/mL. Similar calculations are performed for the remaining beverages. For beer, sodas and orange juice, the serving volume is 355 mL for each beverage, resulting in 71.1 ug/mL of trans-resveratrol to be infused into each beverage. For spirits, the serving volume for spirits is 50 mL, resulting in 499.8 ug/mL of trans-resveratrol infused. For Five Hour Energy®, the serving volume is 57 mL, resulting in 439.1 ug/mL of trans-resveratrol infused. A red wine blank was used as a control in order to show natural resveratrol being present in the beverage.

After the calculations are completed a syringe is used to transfer 0.6 mL of trans-resveratrol tincture to a serving volume of each beverage. The tincture is delivered to each serving volume below the surface of the liquid. In all cases the trans-resveratrol tincture appears to dissolve as a homogenous solution. All beverages receiving the tincture are thoroughly mixed, and a few milliliters of each are transferred to amber-colored sample vials. Samples are stored from each beverage in a refrigerator for analysis.

During analysis the percent of the free trans-resveratrol recovered in the various drinks was determined via HPLC/(+)ESI-MS/MS and HPLC/UV (305 nm).

The results of this experiment are presented in Table 1.

TABLE 1 [t-Rsv] (ug/mL) % Theory Drink# Sample: Theor MS/MS UV MS/MS UV 1 red wine blank 0 <<<spike n/a n/a 2 Red Wine, spiked 134.8 45.8 100.0 33.9 74.2 3 White wine spiked 134.8 63.8 108.5 47.4 80.5 4 Beer; 71.1 34.0 74.3 47.8 104.5 Yuengling 5 Vodka (V), AB 499.8 489.3 549.0 97.9 109.9 Brand 6 Bourbon (BO), 499.8 584.0 534.6 116.9 107.0 Jim Beam 7 5H, Grape 439.1 470.4 473.8 107.1 107.9 8 Diet Coke 71.1 57.1 68.7 80.2 96.6 9 Coke 71.1 49.1 64.7 69.0 90.9 10 Sprite 71.1 53.8 61.4 75.7 86.3 11 OJ, Tropicana 71.1 21.1 41.4 29.7 58.2

It is observed that all beverages receiving the tincture show measurable concentrations of trans-resveratrol. The red wine blank, which is not spiked, is analyzed for natural trans-resveratrol background. While trans-resveratrol is detected in the red wine blank, it is at the instrument's minimum detection limit. Integration of peak areas show the ratio of spiked red wine to unspiked red wine was ˜450. Moreover, the trans-resveratrol in solution is bioavailable because the detection methods can only detect free and unbound trans-resveratrol.

Generally, UV detection reveals higher trans-resveratrol concentrations than did MS/MS detection. MS/MS detection focuses on the 228 mass number, resveratrol's molecular weight. UV detection at a fixed wavelength (305 nm) shows detection of the molecule's conjugated core which includes the two aromatic rings and the adjoining C═C pi bond. Notwithstanding, the recovery values were generally moderate 30-70% to high 70-100%.

Example 10

A tincture of trans-resveratrol with ethanol is prepared with food grade 200 proof ethanol. To deliver 25 mg of trans-resveratrol, 0.60 milliliters of trans-resveratrol tincture is required (42.15 m/mL×0.60 mL=25.29 mg). The serving volume for spirits is 50 mL. 25.29 mg/50.6 mL resulting in 499.8 ug/mL of trans-resveratrol to infuse the spirits with. A syringe is used to transfer 0.6 mL of trans-resveratrol tincture into the vodka and bourbon. The infused drinks show measurable concentrations of trans-resveratrol. The percent recovery of free trans-resveratrol recovered in the vodka during analysis is 97.9% MS/MS and 109.9% UV, and in the bourbon is 116.9% MS/MS and 107% UV. It is appreciated that the percent recovery in some instances is greater than 100% because of +/−17% error because of the techniques used to measure trans resveratrol. As a result these values can be considered to be 100% recovery in the vodka and bourbon beverages. These results show the bioavailability of the trans-resveratrol tincture added to beverages.

Example 11

25 mg of trans-resveratrol powder is added to a serving volume of various drinks including red wine, white wine, beer (Yuengling), spirits such as vodka and bourbon (Jim Beam), energy drinks (5 Hour Energy), sodas (diet Coke, Coke, Sprite) and orange juice (Tropicana). In all cases the trans-resveratrol appears to suspend in solution forming a cloudy layer. All beverages receiving the powder are thoroughly mixed. Each beverage is passed through a 10 micron filter to remove any undissolved resveratrol and any other impurities contained in the resveratrol powder. A few milliliters of each beverage are transferred to amber-colored sample vials. Samples are stored from each beverage in a refrigerator for analysis.

During analysis the percent of the free trans-resveratrol recovered in the various drinks was determined via HPLC/(+)ESI-MS/MS and HPLC/UV (305 nm). It is observed that none of the non-alcoholic beverages (energy drink, sodas, and orange juice) receiving the powder show any measurable concentrations of trans-resveratrol. This differs from the results provided in Example 9 drastically, showing that merely adding powder resveratrol to a beverage does not provide a bioavailable amount of resveratrol. Notwithstanding, it was observed that the alcoholic beverages(red wine, white wine, beer and spirits) receiving the powdered resveratrol did have some amount of bioavailable resveratrol, but below the minimum detection limits of the devices, and thus could not be quantified. This again shows a drastic difference from the results of Example 9, confirming that merely adding resveratrol powder to a beverage minimally delivers a bioavailable amount of resveratrol as compared to the inventive tincture.
